MOSQUITOES AND FLIES REPRODUCTION.
 

   Flies and mosquitoes are insects that go from egg, to larvae, to chrysalis and to adult. These insects vary in size according to the species; they lay a great amount of eggs during each laying, since they have some sensors that favor the election of the laying place and thus assuring a great amount of food for the larvae.

Flies and mosquitoes use a telescopic pipe for copulation and laying the eggs.

   In the female's back end of the abdomen these insects have a segmented telescopic ovipository that can be extended when laying the eggs. According to the insect we are talking about, we find a soft ovipository, it is the case of the common fly, the black fly and the mosquito. The fruit fly has a rigid ovopository to facilitate drilling the fruit. The mosquitoes and the black flies usually lay the eggs in water.

The larvae of mosquito find in water the necessary food for their transformation.
 

   The male has hidden genital pieces and when they copulate the male puts its genital pieces together around the ovipository, to deposit the sperm to fertilize the eggs. Generally one female can lay several egg lots fertilized in one copulation. The common flies are monogamous and they copulate once. Thanks to sexual pheromones produced by the females they are attractive for males. This is why traps of pheromones are very used as method of killing insects.

They can reproduce even when flying.

   The larvae grow quite fast; when the egg is three days old it becomes worm, six or seven days later is a larva and after some changes  becomes a nymph or chrysalid and five days later is an adult.
